Application filed March 25, 1921 Serial No. 455,441.

To all whom it may concern:

Be it known that I, 'IVILLIE A. SHrnLDs, a citizen of the United Statesof America, residing at Birmingham, in the county of Jet 'terson andState of Alabama, have invented certain new "and useful ImprovementsCombination Tools, of which the following is a specification. I

This invention relates to a combination tool adapted for use as a gage,T-square, compass, clamp, and saw-tooth striker or jointing file-holder,all of the various uses being performed by the joint action of the noveltype of rule and clamp block adapted to co-operate therewith H Myinvention will bebest understood by reference to the accompanyingdrawings, which form a part of this specification, and in which Figure 1is a plan view of the tool as adapted for use as a gage;

Fig. 2 is a side view of Fig. 1;

Fig. 3 is a side view inverted showing the tool used as a compass;

Fig. 4 shows the manner of mounting the rule in the block to form a 45angle rule; and I as a clamp or saw striker.

Similar reference numerals refer to similar parts throughout thedrawings.

As illustrated the tool comprises a rule 1 having any desired marginalscales for measurement and provided at one end with an upturned flange 2and at the other end with an angle extension 3, the latter having itstop and bottom edges in line with the top and bottom edges of theruleand having its rule. The wall 4 is formed by a notch 6 in tween thewalls 4 and 5 pre'ferablvcorreot the rule. carries a pointer 7 on thecenter or its upper edge and in line with the commencement of the scale,and the rule is provided with an opening 8 suitable for the insertion ofa ruling pencil. The flange 2 is provided with a threaded opening in'itscenter through which I insert the screw 9, having at its outer end agrip portion 10 and at its inner end being reduced and swaged to holdrotatably thereon a clamp head 11. i Y

I provide a slide block 12 to co-operate with'the rule, and in thisblock I provide a Fig. 5 shows the block as adapted for use:

slot 13 wide enough to permit the rule to be introduced therein as shownin Fig. 1, the block being clamped in any desired position on the ruleby means of a set-screw .14 carrying a rotatable clamp head 15. Thisscrew an extension 16 through which a slot 17 is formed which joinscentrally with the slot 13 and is enlarged-at its base portion 18 whereit joins theslot 13. A clamp plate 19 is set in the slot 17 and providedwith lateral and 5 engaging the side walls of the slot 13, I thentighten the screw 14. thus setting the parts as shown in Fig. 4. For useas a. gage, I set the block 12 at the desired point by measurement withreference ,to the rule scale, then place the point of apencil 22 throughthe hole 8 and slide the 'block against the edge of the strip tobegaged.

For use as a compass, I place a short piece press the pointer 7 into thewood and turn the block, as, shown inVFig. 3, about the pointer, and,the pencil or marker will make a circle. For gaging shingles orweatherboard, I set the block the desired distance from the pointer 7and let the block engage the bottom edge of the board or shingle whilethe pointer 7 is pressed down on the shingle or board for making theimpres- .is mtroducedthrough the .bottom'ot the block as it is normallyused. .The block has of pencil 22 or marker in'the slot 17 and'.' clampit in position by means of screw'21 and plate 19; Ithen invert the tooland sions of nails or "fasteninsrs. For striking or jointing handsaws, Iplacethe saw 23 in a saw clamp as if to file, I then place a flat tile24 in the slot 13 and clamp it in place by a'screw 14. and I then insertthe saw in slot 17 and'tishten screw 21 until the plate19 tits looselyagainst theside of the saw. The saw teeth will be disposed in theenlarged opening 18,the side walls of which will clear the sides of theteeth. By sliding the'block back and'forth, the file 'will strike or:joint all of the teeth.

'For clamping small articles, place the piece to be clamped on the rule1, slide the block 12 against it so as to press it between the block andthe clamp head 11, then tighten screw 10 to clamp the article. The blockitself may be used as a hand vise for small articles by inserting thearticles in the slot 17, and tightening screw 21 to clamp them in placeby means of the plate 19.

All of these various uses are obtained by the improved design of therule and its cooperating slide block which are preferably designed tofunction in all of the various uses pointed out.

What I claim as new and desire to secure by Letters Patent, is

1. In combination, a straight rule having at one end a notch and abevelled edge pro- -viding between them an end extension disposed at anangle to the rule and lying in the same plane therewith, and a slideblock adapted to be mounted on the rule or on its angled element to forma T-square or angled rule.

2. A combination tool as described in claim 1 in which the angle endextension corresponds in width with the rule and has its top and bottomedges lying in the pro jected lines of the top and bottom edges of therule.

S. A combination tool comprising a slice block and a rule having abeveled end edge, and a notch in one lateral edge to provide an edgeparallel with said beveled edge of tl e rule and forming an angled endextension .on the rule adapted to be received in the block.

In testlmony whereof I afliX my signature.
